Abstract:With the rapid development of smart grids, grid companies have accumulated a large amount of data in the status of power transmission and transformation equipment, power grid operation, user power consumption, enterprise management, and meteorological environment. In the face of big data sets, traditional visualization methods have presented problems of insufficient processing power and information expression capabilities. Therefore, this paper studies the WEB data visualization technology, and designs a matching visualization technology scheme for the characteristics of power big data in many different application scenarios, and analyzes the characteristics and advantages of the scheme. The proposed scheme provides a reference and useful practice for the visualization of grid big data application scenarios, greatly improving the utilization and value of power big data.
